Do not carry one daily anymore, but when I do, carry a Bic for lighting stuff. When I was in the Army, ended up carrying two, smoked cigars usually when off duty. Whenever I had one out, sure enough somebody would run up and ask for a light. Would pull one of the Zippos out of the left pocket and oblige him. When I would light my own, did it with the one in the right pocket. The one on the light was fueled with lighter fluid. The one on the left was fueled with lighter fluid, and diesel fuel. First puff and the fellas bumming a light sure got a funny look on their puss.
